"There are many deployment scenarios that require an egress Label Switching Router (LSR) to receive binding of the Resource Reservation Protocol - Traffic Engineering (RSVP-TE) Label Switched Path (LSP) to an application and a payload identifier using some ""out-of-band"" (OOB) mechanism. This document defines protocol mechanisms to address this requirement. The procedures described in this document are equally applicable for point-to-point (P2P) and point-tomultipoint (P2MP) LSPs."
